Air deliveries bring NASA's Perseverance Mars rover closer to launch

2 days 8 hours ago
Progress continues to speed along as NASA's Perseverance rover readies for its launch this summer. On May 11, the rover team at the agency's Kennedy Space Center in Florida received the tubes tasked with holding the first samples collected at Mars for eventual return to Earth. A week later, the Atlas V launch vehicle that will hurl Perseverance to the Red Planet arrived at the launch site. Working together, personnel from NASA's Jet Propulsion Laboratory in Southern California and United Launch Alliance in Centennial, Colorado, were also able to extend the rover's launch period by six days, from Jul. 17-Aug. 5 to Jul. 17-Aug. 11.

ALMA spots twinkling heart of Milky Way

2 days 8 hours ago
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due to the rotation of radio spots circling the supermassive black hole with an orbit radius smaller than that of Mercury. This is an interesting clue to investigate space-time with extreme gravity.

Space Force is starting to train its soldiers to fight… in space?

On February 19, 2019, the U.S. Space Force (USSF) was officially created with the signing of Space Policy Directive–4. This effectively broke it off from the U.S. Air Force Space Command (AFSC) and made it into the sixth and youngest independent branch of the armed forces. Since then, the USSF has established a headquarters, taken on staff from the U.S. Air Force, and even produced a recruitment video.

How galaxies and black holes grow together

3 days 9 hours ago
Over the past two decades, astronomers have concluded that most, if not all, galaxies host massive black holes at their centers—and the masses of a black hole and its host galaxy are correlated. But how are the two connected? Now, a University of Hawaiʻi at Mānoa Institute for Astronomy (IfA) student participating in the National Science Foundation's (NSF) Research Experiences for Undergraduates (REU) program, may have revealed part of the answer.

NASA's OSIRIS-REx ready for touchdown on asteroid Bennu
